Built from high speed steel (HSS) with no coating, it features a 0.125-inch cutter diameter, a 0.375-inch length of cut, and a 1\/4-inch shank diameter. The upcut flute geometry pulls chips away from the workpiece and toward the spindle, helping keep the cut path clear and reducing heat buildup. With a helix angle ranging from 19 to 32 degrees and a right-hand cutting direction, this bit is suited for clean, controlled cuts in softer metals and natural wood. Overall length is 2.625 inches with a 2.25-inch shank length.\u003c\/p\u003e\n\u003cp\u003eThis bit is well matched to CNC routing and high-speed spindle applications in woodworking shops and light fabrication environments handling aluminum and natural wood. The 1\/8-inch cutter diameter makes it appropriate for narrow slot work, profiling, and detail cuts where a larger diameter tool would remove too much material. Tooling engineers, CNC operators, and experienced machinists are the typical end users. The single-edge design supports higher feed rates in softer materials where chip evacuation matters more than surface finish on the cut wall.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eUpcut single-edge flute for efficient chip evacuation during routing\u003c\/li\u003e\n  \u003cli\u003eHigh speed steel construction compatible with aluminum and natural wood\u003c\/li\u003e\n  \u003cli\u003e0.125-inch cutter diameter for narrow slot and detail routing applications\u003c\/li\u003e\n  \u003cli\u003e19 to 32 degree variable helix angle supports clean entry and reduced deflection\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction, uncoated finish, no pilot bearing\u003c\/li\u003e\n  \u003cli\u003ePart of the ONSRUD 40-000 series for consistent tooling standardization\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC routers and spindle tooling setups accepting a 1\/4-inch shank.

Power down and fully de-energize the spindle before inserting or removing the bit. Seat the shank fully into the collet to the recommended engagement depth and torque the collet nut per the spindle manufacturer specifications. Inspect the cutting edge for chips or wear before each use, as HSS tooling in metal applications is subject to edge degradation at elevated feed rates or spindle speeds.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.625 inches (2-5\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Length\u003c\/strong\u003e: 2.25 inches (2-1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBit Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Upcut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRouter Style\u003c\/strong\u003e: Single Edge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 19 to 32 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Natural Wood\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePiloted\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 40-000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ONSRUD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 40-001\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ONSRUD","offers":[{"title":"Default Title","offer_id":67909512266034,"sku":"40-001","price":33.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d21388383ab5c1743200474a38577e8.jpg?v=1791188299","url":"https:\/\/voomisupply.com\/products\/onsrud-40-001-upcut-spiral-router-bit-1-8-inch-hss","provider":"Voomi Supply","version":"1.0","type":"link"}
